What is the value of a 1946 red comet fire extinguisher?
little to nothing. if the liquid is present, its toxic and shipping it is illegal. If you can find a collector locally who doesnt mind having a glass vial of poison, maybe you can sell it.
A case of six bulbs in mint condition, with the original wooden box, felt lining and mounting would fetch $60-$150.
A single bulb, $5-$20.
What fire extinguisher do you use for a car fire?
A car extinguisher may be necessary for putting out several different types of fires, so it should be a Class A:B:C extinguisher, normally dry powder. For an irreplaceable classic, one might consider a CO2 or a "clean agent" extinguisher, to avoid the damage potential of dry powder chemical extinguishers.
What is a disadvantage of Halon fire extinguishers?
Halon inhalation can affect the cardiovascular and nervous system and can cause death in humans and other mammals at HIGH CONCENTRATIONS.
It also displaces breathable air within the compartment.
In theory, a properly installed and calibrated system will include enough oxygen to support human life, but in practice it would be wise to immediately evacuate anyone who does not have self-contained breathing apparatus.
Does a fire extinguisher have water?
There are different types of extinguisher materials for different types of fire - some fires can be fought with water, but for other fires the use of water would actually make the fire worse (for example, a fire in pan of oil attacked with water will flash boil the water and blow burning oil all over; Attacking an electrical fire with a stream of water will lead to electricity being transmitted along the stream and electrocuting the firefighter. As a result, the contents of any given extinguisher will depend on the sort of fire that would reasonably be expected in the area where it is kept.
Fires can be classed as follows:
Class A:
SOLIDS such as wood, paper, cloth, plastic etc
Class B:
FLAMMABLE LIQUIDS such as paraffin, petrol, oil etc
Class C:
FLAMMABLE GASES such as propane, butane, methane etc
Class D:
METAL FIRES (aluminium, magnesium, titanium etc.)
Class E:
Fires involving ELECTRICAL EQUIPMENT
(In the USA, these are Class C fires)
Class F:
Cooking OIL & FAT etc
(In the USA, these are Class K fires)
To fight these fires, there are specific extinguishers for each class:
Water Fire Extinguishers:
The cheapest and commonest fire extinguishers. Used for Class A fires. Should not be used with Class B, E and F fires.
Foam Fire Extinguishers:
More expensive than water, but more versatile. Used for Classes A & B fires, but not for Class E, but are safer than water if inadvertently sprayed onto live electrical apparatus.
Dry Powder Fire Extinguishers:
Can be used on classes A, B & C fires. Optimum extinguisher for fires involving running liquid (Class B). Special powders are available for class D (metal) fires.
CO2 Fire Extinguishers:
Carbon Dioxide is ideal for Class E fires, and will also extinguish class B fires but disperses quickly and this can allow the fire to re-ignite.
There are also specialist extinguishers for use with Class F and Class D fires.
What should you do when a fire continues to grow when you are fighting it?
if the fire spreads to the curtains however even a garden hose might not deliver enough water to put out the fire
Where do you aim a fire extinguishers stream when extinguishing a fire?
At the base of the fire and use a sweeping motion
What kinds of fire that foam extinguisher should be use on?
Foam spray extinguishers are not recommended for fires involving electricity, but are safer than water if inadvertently sprayed onto live electrical apparatus.
Class B
Do fire extinguishers really expire?
Yes. This is why it is important to have them serviced regularly.
What kind of fire extinguisher can put out a electrical fire?
The extinguisher that has only a green triangle on it would be a really BAD choice because it probably contains water for putting out Class A fires of ordinary combustibles.
An electrical fire (Class C) is signified by the letter C in a blue circle.
Or, you can turn off the electricity and use any extinguisher appropriate for the type of fire that was started by the electricity's heat.
Will the chemicals in a fire extinguisher kill bees?
Yes they will. The smoke itself will kill bees, because they won't be able to see or breath, they are too small.
What method or fire extinguishers could be used to put out a burning paper in a metal bin?
Firstly, there are 5 different classes of fires, and a fire triangle.
With the fire, look at what is the cause of it. As it is a metal waste bin fire, I would assume that the paper has caught on fire for whatever reason, therefore it is an oxygen fire. With that information in mind, read my next points.
Using an ordinary combustible such as paper/wood/cloth; creates a Class A fire.
Extinguishing most fires and Class A fires, a regular water fire extinguishers would eliminate your dilemma. It is the cheapest and the most widely used extinguisher, so I would expect that your issue is related to that waste bin fire.
I hope my recompilation of statements and facts has led you to the correct conclusion in your dilemma. :)
Can we use helium as Fire extinguisher?
No, helium is not used in fire extinguishers. We find carbon dioxide (CO2) in some extinguishers, but not helium.
What does the red fire extinguisher contain?
A dry chemical fire extinguishing powder. or CO2 or halon 1211 and other products. The color red is the most used color for fire extinguishers, but white, blue, yellow, purple and other colors might also be found. There appears to be no fixed standard.

What type of extinguisher is needed to put out an alcohol fire?
FFFP foam is alcohol resistant and is effective on a wide variety of Class B materials such as alcohol, polar solvents, hydrocarbons, and combinations such as gasohol. Applying FFFP foam to non-ignited Class B liquid spills will seal the surface minimizing the chance of serious fire.
See the related link for more information. Also refer to NFPA-10 for more specific details.
How many fire extinguishers are required aboard an 18-foot powerboat with installed fuel tank?
At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat, unless it is under the following exception:
- "motorboats less than 26 feet in length,
- propelled by outboard motors and
- not carrying passengers for hire, need not carry such portable fire extinguishers if
- the construction of such motorboats will not permit the entrapment of explosive or flammable gases or vapors" [bullets added]
A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc).
